Solenoid modulator valve AW5550 OS

Solenoid modulator valve AW5550 OS • Valve • End Plug Symptoms: • 2-3 Flare • 5th Gear only • Delayed Forward • Low line pressure • No 3rd • No 4th • No 5th • No lockup Cause: The OE steel valve results in excessive clearance during hot operation and frequently sticks when cold. Bore wear can reduce available solenoid modulator pressure, resulting in delayed forward, flare on 2-3, TCC slippage or soft shifts overall. Bore wear at the inboard end results in excess solenoid pressure, improper gear or harsh shifts. Correction: The Sonnax oversized solenoid modulator valve made of wear resistant hardcoat anodized aluminum re-establishes proper pressures. Additional support is given to the valve by adding length to the outboard spool.
